Advertising Options:

Please refer to the screen capture below for Banner Ad, Highlighted Ad, and Hyperlinked
Logo formats and locations. Banners and Hyperlinked Logos appear on every page of RF
Cafe as shown. Hyperlinks point directly to your website. Please
contact
me if you are interested. Web page layouts do change occasionally, but order of ad
precedence is always retained.

Please contact me with any questions - it is simpler
than it might look!

NOTE: I reserve the option to refuse ads which I do not feel are appropriate for the
RF Cafe mission.

3rd-Party Advertising Options:

3rd-party advertising on RF Cafe is being provided
by Google Ad Words,
IHS
(GlobalSpec), and
Yahoo!|Bing Network. Please contact them via the provided hyperlinks for information;
customer service agents are available for assistance if needed. Note, however, that
the appearances of 3rd party ads represents only about 5% of the total.

If
this page is still available by the time you click the link, it has
a good synopsis on click-through rates (CTR) and cost per click (CPC). For the general
Technology category, CTR is 0.85% an CPC is $0.20 based on ad impressions on websites
like RF Cafe that might host Google Ads. Keep in mind that Technology includes everything
from cellphones and televisions to power dividers and coaxial cable. My guess is that
cellphones and TVs make up a much larger portion of that 0.85% than do power dividers
and coaxial cable.

URL.

Important Notes:

Pixel dimensions and maximum file sizes listed are firm. If you have trouble meeting
the file size, I will be glad to help - there has never been an ad I couldn't fit.

I do not collect page traffic or link click statistics for advertisements. Your website
server statistical analysis is a much better reporter of inbound links from RF Cafe than
I or anyone else can provide.

To the best of my knowledge the page layouts shown are representative of all pages
on RF Cafe.

I make page layout changes from time to enhance performance, but regardless of the
layout, your ad(s) will retain relative location order.

78x26-px logos in upper right corner are provided at no additional
cost, and are subject to size, location, and format change as deemed necessary for optimizing
space usage. These appear on all pages with every page view.

* Your banner(s) will be displayed at approximately
a 1:3 rate I usually run third-party advertisements or my own RF Cafe software ads along
with private advertisers in the banner slots, at a display rate of about 1:10.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
